The accessory that most symbolizes today's scuba diver, apart from the fins, mask and tank, is the wetsuit. Wetsuits are usually made of a combination of neoprene rubber and synthetic fabrics. They have come a long way since the early days of suit pioneers such as the O'Neill Brothers Santa Cruz surf suits. The make-up of today's wetsuits has evolved into a wide variety of fabric weaves, designs, colors and types of material densities. With the many brands that each offers their unique take on each part of the divers dress, consumers are spoiled for choice.
